[Spice-devel] spice 0.6.3 slower than 0.4?

Hi

I tested with spice 0.4 server and a spice 0.8 client but that's also
slow. Both versions use a different mechanism to exchange data (redhat
vdi port vs virtio-serial device) so I didn't expected it to perform
well.

Is there a way to check when spice detects a movie and enables
compression? Or are there others tests I can perform to pinpoint the
poor performance I experience with spice 0.8?

Kind regards,
David

No, that's unrelated. That's talking about jpeg support for images,
which
is used to reduce bw in wan environment.

Between 0.4 and 0.6.3 we ripped out the ffmpeg reliance and put in new
mjpeg
code. So this regression might (very probably I guess) be related to
this.
This affects just the compression btw, the rest of the video code (i.e.
discovering repeated updated to the same region) remained unchanged
afaik.

There is nothing to see in the logs below, they look normal.
